摘　　要：固相萃取(SPE)技术结合毛细管气相色谱(GC-μECD),测定了饮用水源地太湖梅粱湾水体中内分泌干扰物阿特拉津的含量,并用GC-MS进一步验证了分析结果。检测下限为10 ng/L,方法回收率为75.58%~97.79%,RSD为0.38%~4.50%,在10 ng/L^3 640μg/L保持线性,其线性相关系数为0.999 4。太湖梅梁湾水体中阿特拉津质量浓度在21.3~613.9 ng/L,污染来源可能为太湖周围的农作区。A capillary gas chromatography method with SPE preconcentration was developed for determination ot atrazine in water of Taihu Meiliang Bay, following a GC-MS-SIM confirmation. The determination limit was 10 ng/L. Method recovery and RSD is 75.58-97. 79% and 0.38%-4.50%, respectively. Linearity range between 10 ng/L-3 640 μg / L and the regression coefficient is 0. 999 4. The concentration of atrazine in water of Taihu Meiliang Bay was in the range of 21.3 to 613.9 ng/L. The source of atrazine pollution might be from the drainage area of Taihu Lake.
